I seem to be having a problem with my site. Two people who tried to go on it mentioned that they got a message saying there is a problem with the website's security certificate. Any clue on why this might be or how I can fix it?

I've been experiencing problems with the WordPress site http://himmlische-antworten.net/ which I administer.
When I try accessing the site using SSL (via https://) I get a certificate warning in Firefox, Chrome and IE (Error in FF: "Untrusted Connection" / "ssl_error_bad_cert_domain") and can't access the site unless I add a security exception. The domain is registered via the wordpress.com Premium Package. When accessing the site under it's "native" domain (https://himmlischeantworten.wordpress.com) the problem doesn't occur.

Does anyone know how I can solve this? Is there a manual way to renew the SSL certificate?

thanks for your reply. You are correct, using http:// works just fine. The problem is that some search engines link to https:// by default, and people like me who use browser plugins that redirect to HTTPS wherever possible see the error as well. Some less technically inclined people might not know what to do when faced with the error and thus, I'm losing traffic, which is unacceptable.

The domain is in fact registered through WordPress and not an external registrar, so I can't make any changes to the domain, further than what is offered in the WordPress dashboard, which doesn't include what I need.

I have same situation on two blogs both of which have custom domains. I believe nothing has changed and Staff still cannot issue SSL certificates for custom domains (mapped or registered at WordPress.com) at the moment.

Hello, I just did a reblog from a certain site that was giving away a free giveaway.. now when I click on that site from my page, an Error message appears saying something like.. Attackers must be present to snatch away your password or credit cards etc blah blah...

May I know why this is being happening? Should I remove the reblogged content altogether? Or is it something else?

You won't be able to change the actual links in the reblog, so your readers might still experience this problem. You can perhaps give them the explanation I gave you via a comment on that reblogged post of yours.

I just noticed an exclamation point to the left of my URL and also a triangle next to the sync icon to the right of it. When I hover over the exclamation point, the pop-up tip states, "This website does not supply identity information." How do I correct this? Thank you.

Will you provide a screenshot please? I'll tag this thread for Staff attention. You can use http://snag.gy/ to share screenshots and link to them here. If you use the WordPress.com guide for screenshots http://en.support.wordpress.com/make-a-screenshot/ you can and upload it to your Media Library, and return to this thread to provide the file name so Staff can examine it.

Just one screenshot from http://snag.gy/ is fine. I believe what you are referring to could be the SSL security Staff have implemented re: changing our http:// links to the more secure encrypted https:// links. However, Staff will confirm that when they get to this thread.

Please see the HTTPS support page. http://en.support.wordpress.com/https/ Note that SSL certificates need to be signed to a specific domain, and WordPress.COM cannot provide certificates for mapped domains at this time, so our certificate is signed for WordPress.com. That may result in browser warnings if you access your custom domain at https://hearttoheartlomilomi.com/ instead of the HTTP version at http://hearttoheartlomilomi.com/ The developers who are working on this hope to have HTTPS support for all WordPress.com users this year, but no other details are available at this time.
